What's this test for?

This test is ideal if you're experiencing unexplained blood clots, or if you've had recurrent pregnancy loss and want to understand why. It looks for lupus anticoagulants, which are antibodies that can raise the risk of dangerous blood clots and pregnancy complications. Many people never get an answer for these issues, and this test can help identify a hidden autoimmune cause.

What's included in this test?

This panel uses a screening step followed by automatic reflex testing only if needed, so you get a complete answer without ordering multiple separate tests. The confirm step and the 1:1 mixing step work together to distinguish a true antibody problem from other causes of a prolonged clotting time, like a factor deficiency. This layered approach follows international guidelines for properly diagnosing lupus anticoagulant.

What happens after I get my results?

Your results will show up in your account with each part of the panel explained, including what a normal versus abnormal range looks like. If the screening test is positive, the confirm and mix steps built into this panel automatically help clarify whether lupus anticoagulant is truly present. Depending on your result, next steps may include retesting after a few months or discussing anticoagulant therapy if you already take blood thinners. You can download a standard lab report anytime and use the trends feature to track changes if you retest in the future.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. This turnaround allows time for the initial screen and, if triggered, the additional confirm and mix testing to be completed and reviewed for accuracy. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is a good option for anyone who has had an unexplained blood clot (like in the leg or lung), a stroke at a young age, or multiple miscarriages, especially after the first trimester. It's also useful for people who have another autoimmune condition, such as lupus, and want to check their clotting risk. If you take certain blood thinners, mention this on your order confirmation since it can affect results.

What symptoms indicate I may need this test?

Watch for symptoms like sudden leg swelling and pain, unexplained shortness of breath, or a history of miscarriages, particularly later in pregnancy. Some people also notice skin discoloration or a lace-like rash on their legs. If you've had more than one unexplained clot or pregnancy loss, this test can help find out if antibodies are the cause.

What is a lupus anticoagulant and why does it matter?

A lupus anticoagulant is a type of antibody that mistakenly attacks proteins involved in normal blood clotting. Despite the name, it isn't limited to people with lupus and doesn't cause bleeding — in fact, it raises your risk of forming clots. Finding out if you have this antibody helps explain unexplained clotting events or pregnancy losses so you can take steps to lower future risk.

What does a positive result mean?

A positive result means the antibody was detected and confirmed through the follow-up testing steps included in this panel. This raises your risk of blood clots and, in pregnancy, complications like miscarriage or preeclampsia. It doesn't mean a clot will definitely happen, but it's important information that can guide preventive steps like closely monitoring symptoms or starting a blood-thinning medication.

How often should I retest?

Guidelines generally recommend retesting at least 12 weeks after an initial positive result to confirm the antibody is persistent rather than temporary. Temporary positives can happen after infections or with certain medications. If your first test is positive, plan for a repeat test around that timeframe to get a clearer picture.

What should I do if my results are abnormal?

If your screening result comes back abnormal, don't panic — the built-in confirm and mix steps in this panel are designed to clarify the finding automatically. If you have symptoms like sudden leg swelling, chest pain, or trouble breathing, seek medical care right away since these can signal a clot. Otherwise, plan to retest in about 12 weeks as recommended and keep a record of your results using the trends feature in your account.
